Instead of popping it yourself with a needle آپ could try bathing your feet and ankles in warm water. Not boiling, but not tepid either. It usually takes around 2 days constant bathing, drying, changing the water etc to pop them.
Or, like others have کہا - pop it with a needle. But make sure آپ sterelise the needle first سے طرف کی putting it into a cup of boiling water for a minute. If آپ don't and the needle has germs on it, it could do مزید damage then good.
